After issuing repeated warnings, Egyptian security forces on Aug. 14 raided two protest sites in Cairo that for weeks had been occupied by the Muslim Brotherhood and supporters of deposed President Mohamed Morsi. Carnage followed. Inevitably, police and Islamists accused each other of firing the first shots, but the majority of the protesters were unarmed. By day's end, the official death toll had exceeded 200 and was climbing fast. The violence also spread to other parts of the country.
